"Introducing an all-new innovative turntable controller, DJ Hero transforms players into DJs who rule the club scene by creating original mixes of popular songs and music from the world's most exciting artists and DJs."

That's as much detail as we have at this stage, but if you're searching for further clues as to the way the game will be played, you can also check out the renders of the companion DJ Hero controller.

This, predictably enough, is styled like a turntable, and has three coloured buttons on the top.

DJ battle

The official launch of DJ Hero follows a period of legal wrangling, during which Activision was accused of attempting to scupper the launch of rival game Scratch: The Ultimate DJ.

In March, Activision was ordered to return the Scratch source code to original publisher Genius, having acquired it when it bought 7 Digital, the company that was developing the game, earlier this year.

Activision has also announced that Guitar Hero 5 and Band Hero (a family orientated version of Guitar Hero) will be released in 2009.
